Having a problem mixing HTML and PHP

[tony@tony.com]

I am trying to use a form with a button that calls a verification script
but can't seem to get the script to run at all - can anyone tell me if
this SHOULD work in a forms onCLick or have I got the syntax wrong?

The function is previously included with include_once('l ibrary.php');
This seems to work ok. I dont get any php errors if I turn on reporting.
The function checks out ok on its own. I've also tried a simple echo with
no luck. the page is called myform.php (not .html)

The form button has:

<input type=button name="btOne" value="Click-Me" id = "mButton" onClick =
"<?PHP verify(); ?>" >

I did think you could do this - am I wrong?
(Incidently I'm also having trouble getting onBlur to work in a similar
form with PHP.)

thanks.

PHP != javascript.

It runs on the server not onthe clients machine, so simply speaking as soon
as the content is sent it's job is done. It can't tell what you are doing in
a html page. If you want PHP to handle (new) values, you will have to send
them to the server. In most cases this means requesting a new page.

PHP is processed on the server, and does this *before* the user ever
sees the HTML page, meaning that the verify() you have is called before
the page is displayed to the user.

Rather use a submit button and let the script referenced to in the
"action" attribute of the <form> tag handle the verification of the
fields.

A process like the one you're shooting for can be done using AJAX, but
in this case, that could be more trouble that it's actually worth.
